NON-REFILLA'BLE BOTTLE.

Specification of Letters Patent.

Application filed August 15, 1912.

Patented Sept. 5), 1913. Serial No. 715,146.

1 'o aZZ whom it may concern Be it known that I, PAUL T'IAAK, a citizen of the United States of America, residing in the city and county of Philadelphia, in the State of Pennsylvania, have invented a certain new and useful Improvement in Non- Refillable Bottles, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part thereof.

The object of my present invention is to provide a simple, effective and practically feasible bottle closure adapted to be inserted in the neck of a filled bottle, and which while permitting the bottle to be readily emptied will prevent any subsequent refilling of the bottle.

The various features of novelty which characterize my invention are pointed out with particularity in the claims annexed to and forming part of this specification. For a better understanding of the invention, however, reference should be had to the ac companying drawings and descriptive matter in which I have illustrated and described a preferred embodiment of my invention.

Of the drawings: Figure 1 is a sectional elevation of a non-refillable bottle equipped with a closure constructed in accordance with my present invention. Fig. 2 is a section on the line 22 of Fig. 1, and Fig. 3 is a section on the line 3-3 of Fig. 1..

The neck of the bottle A shown in the drawings is formed with a valve seat A at its inner end. As shown this valve seat is conical. At the outer side of the valve seat A the inner wall of the bottle is provided with a shoulder which as shown is in the form of a circumferential rib A The i11- ternal diameter of the portion A of the bottle neck immediately adjacent the rib A on the outer side of the latter is prefe "ably slightly larger than the internal diameter of the outer end portion A of the bottle neck or at least than the inner end of the latter if the passage through the portion is flaring as may well be the case.

The bottle neck portion A is adapted to receive a stopperF, such as an ordinary cork to prevent leakage from the bottle during its transportation, or other handling.

The valve seated port A is controlled by a valve member B, which is formed on its inner side with a cavity B for a purpose hereinafter explained, and is formed on its outer side with an axially extending hollow stem 1. which is open at its outer end. The stem B is telescopically received in the open-ended tubular projection C formed on the inner side of a disk likc body C inserted in the neck of the bottle. The diameter of the disk C is preferably just small enough to pass through the portion A" of the bottle neck, but is separated from the portion A of the, bottle neck by a narrow annular space through which liquid in the bottle may flow when the bottle is being emptied. The member C, which as well as the valve member B, may well be made of glass, is intended to be inserted in the neck of the bottle after the latter has been filled, and to be held against subsequent removal. The means shown for holding the member C against removal comprises a bushing I) which surrounds the tubular extension C and has its periphery in engagement with the inner surface of the bottle neck portion A, the engagement of member I) with the member C and its extension 0 on the one hand, and with the neck of the bottle on the other hand being of such a character as to resist the movement of the member C relative to the member D, or of the latter relative to the neck of the bottle in an outward direction under any force which it is practically feasible to apply to the member C. It is possible to accomplish this, for instance, by the use of a suitable cement. In practice, however, I prefer to make the bushing D of a suitable resilient material such as cork and to rely upon the frictional grip with which it engages the neck of the bottle and the member C to hold the parts in place. The cork member D in this case should, in its uncompresscdstate, be larger in diameter than the internal diameter of the bottle neck portion A into which it is forced. The effect of the frictional grip with which the bushing D ei'igages the contacting parts, may be augmented by providing a rib or ribs, such as the rib C formed on the inner end of the tubular extension C of the member C. The member I) is formed with axial passages at its periphery through which the liquid containcd in the bottle may flow when the bottle is being emptied. lVhen the parts are in place the inner end of the bushing D bears against, and its further inward movement is prevented by the rib A The valve member 13 is normally held against its seat by a light spring l'] located spring E are inserted in the neck of the bottle after the latter is filled. lVhen, thereafter it is desired to empty the bottle, this may be effected after the stopper F is removed by simply inverting the bottle in the usual manner. The weight of the valve member B plus the pressure exerted on the latter by the liquid within the bottle will compress the spring E and permit the valve member to move away from its seat, whereupon the liquid will flow out of the bottle through the path including the annular space between the valve member and its seat, the channels 1), the annular space between the disk C and the surrounding portion of the neck of the bottle. While the bottle may thus be readily emptied, it cannot be refilled, for as soon as the bottle is inverted and the valve member B is relieved from the weight of the liquid filling the cavity B while the bottle is emptying, the spring E will move the valve member against its seat. It is impossible moreover to fill the bottle by maintaining it in an inverted position with the valve cavity B filled with liquid and exhausting the air from the bottle, and then submerging the neck of the bottle in liquid exposed to atmospheric or other pressure in this case as soon as the liquid with which it is attempted to refill the bottle rises to the inner end of the bottle neck the flotative efi'ect of this liquid will, in conjunction with the spring E, lift the valve member B against its seat. With theconstruct-ion described it is obviously practically impossible to insert through the restricted annular space surrounding the disk C any hook or other instrument which would be adapted to get a grip on the valve member B sufficient to hold it away from its seat when the weight of the liquid filling the cavity 13' does not effectually oppose the closing tendency of the spring E.

It is to be noted, that any tendency of the valve member B to stick against its seat when the bottle is wholly or partially filled, is opposed by the entire weight of the column of liquid above the valve member B when the bottle is inverted, and furthermore, the effect of the weight of this liquid column may be materially augmented by shaking the bottle more or less violently while holding it in the inverted position.

ll hile in accordance with the provisions of the statutes I have illustrated anddescribed the best forms of my invention now known to me, it will be apparent to those skilled in the art that changes may be made in the form of the apparatus disclosed without departing from the spirit of my invention, and that under certain conditions some features of my invention may be used to advantage 'without the corresponding use of other features.

Having now descrlbed my lnvention, what I claim as new and desire to secure by'Letters Patent, is

1. The combination with a bottle having 7 its neck formed with an internal valve seated port at its inner end,of a valve adapted to engage said seat and close said port, said valve being formed with a liquid h0lding cavity on its inner side and with a hollow stem on its outer side, a member mounted in and insertible through the outer end of said neck and comprising a disk-like body substantially filling the said neck, but separated from the surrounding portion of the neck by a narrow annular space and formed with a tubular projection on its inner end telescopically receiving said hollow stem, a spring received within said hollow stem and tubular projection and nor mally holding the valve against its seat with a force exceeding the weight of the valve member when said cavity is empty, but less than the weight of the valve member when said cavity is filled with liquid, and means for holding said disk-like body against removal from the neck of the bottle. 1

2. The combination with a bottle having an integral neck formed with an internal valve seated port at its inner end and having an internal diameter at its outer end reduced slightly from the internal diameter of an intermediate portion of the neck, of a valve adapted, to engage said seat and close'said port, a valve retaining and guiding member mounted in and insertible through the outer end of said neck and comprising a disk like body located within the said intermediate portion of the neck and of a diameter substantially equal to the reduced internal di- 'ameter of the outer end portion of the neck slightly from the internal diameter of an intermediate portion of the neck, of a valve adapted to engage said seat and closersaid port, a valve retaining and guiding member mounted in and insertible through the outer end of said neck and comprising a disk like body located withln the said intermediate portion of the neck and of a diameter substantially equal to the reduced internal diameter of the outer end portion of the neck and separated from the surrounding portion of the neck by a narrow annular space, said member also comprising a portion of reduced diameter at the inner side of said body portion, and means for holding said member against removal from the neck of the bottle comprising an elastic bushing surrounding said portion of reduced diameter and compressed between it and the surrounding portion of the bottle neck and formed with channels extending through the bushing from end to end.

4. The combination with a bottle having an integral neck formed with an internal valve seated port at its inner end and having an internal diameter at its outer end slightly reduced from the internal diameter of an intern'iediate portion of the neck, of a valve adapted to engage said seat and close said port, and formed with a stem on its outer side, a valve retaining and guiding member mounted in and insertible through the outer end of said neck and comprising a disk like body portion located within said intermediate neck portion and of a diameter substantially equal to the reduced internal diameter of the outer end of the neck and separated from the surrounding portion of the neck by a narrow annular space, said member also comprising a tubular portion secured to the inner side 01' said body portion and of less diameter than the latter, adapted to receive and guide said valve stem, and provided at its inner end with an outwardly extending rib, and: means for securing said member against removal from the neck of the bottle comprising an elastic bushing surrolmding the tubular portion of said member between said rib and said body portion and compressed bet-ween said tubular portion and the surrounding portion of the bottle neck and formed with channels extending through it from end to end.
